[goose101]

Thanks for all the info, really helpful.

Re:Towser - do you know how the performance figures for grooved rwy were derived? Was it using flight testing?

is it the case that when wishing to make use of grooved rwy characteristics you must conduct flight tests to establish the data?

Thanks in advance again.
